    E.6 Gauge Markings E.6.1 Caution and Warning Alerts The GI 275 EIS will generate alerts for gauges with configured red or yellow markings by highlighting the numerical value in a red or yellow background, respectively. For strip and digital readout gauges, a flashing alert triangle is generated in the top left of the display in addition to highlighting the numerical gauge value.

    E.6.2 Gauge with Varying Arc Width The GI 275 EIS display does not provide varying gauge arc width configuration options, as seen in Figure E-21. If a gauge that contains a varying arc width is being replaced, it must be configured so that the arc length is continuous for the intended length of the colored arc.
